Quick installation The busbar’s junction and fixing systems have been designed and created to install busbars easily. In a cable and tray system, the time required to install only the tray is the same used to install a complete system in busbars. Furthermore, given the same capacity, a power busbar, which generally has aluminium conductors, is much lighter than a system made with (copper) cables: lighter weights require a lower number of supporting frames or, in any case, more simple and inexpensive supporting frames. That is why the installation time of a busbar is obviously shorter than a similar...
